As far as VFX challenges go, the latest Chemical Brothers promo Wide Open (feat. Beck) is a doozy - a woman dances around a warehouse space as parts of her body are revealed as 3D-printed lattice constructions - in one four and a half minute shot. That’s right, one shot. If matching the dance performance with see-through body parts wasn’t hard enough, the effect had to last almost 6,800 frames. But The Mill London was up to the challenge, collaborating with directing duo Dom & Nic and implementing meticulous tracking, mocap data and even a bespoke tool for producing clean plates to make the promo possible. fxguide spoke to key members of The Mill's team to break down, step-by-step, how this incredible piece was brought to life.
